ETHA asa leak

i played a coulpe of games with my etha and after a while the asa became loose and started to leak. it leaks very minor. i tightened up the screws to the asa and it stopped leaking then it came back.
Also i dont dont how far back i put the asa. cause with the etha you can move it up and down. im guessing thats the problem , but i dont know.

Where exactly is it leaking from on the asa? How far forward or back on the rail shouldn't matter. It's made to be able to be adjusted so that you can make the gun a little farther or closer to you, for comfort.

it leaks at the end of the macroline. sometimes it leaks and some times it just stops
